Thanks! Good news, i found same tires i used on 28 inch wheels for 26 inch rim, in three different width: 1.3, 1.6 and 2.0! So i would be able to keep same look on a smaller wheel too! There are two reasons i am not going for shorter cranks. First is if it does not feel good without the fender, it would get even worse when i put it on! This is going to be a daily bike probably, so fender is a must. Second reason is that i am quite a tall guy, so my legs are long too. Pedaling on 155mm cranks is quite uncomfortable for me already, they feel short and i feel i have to push way harder to achieve same torque on the wheel. I'd gladly go for more then 175 actually, but they are too expensive since not many people use them. Now i have 170mm temporary cranks, and probably the ones i am going to use will be 175mm. Chances are this is going to be the bike i am going to go with to the Netherlands this summer, so i am planning to make few thousands km on it. I still might change my mind on which bike i am taking, but better to be prepared! And on the trips like that optimal ergonomy is crucial.
